Matelea falcata Juárez-Jaimes, G. M. Hernández-Barón & W. D. Stevens (Apocynaceae, Asclepiadoideae) is described and illustrated. This new taxon grows in secondary vegetation derived from semi-evergreen forest, around the Loltún caves in the state of Yucatán, Mexico. It resembles M. gentlei (Lundell & Standl.) Woodson; it is recognized by its pinwheel-like flowers due to the conspicuous falcate apices of the corolla lobes, which are fleshy at the base. Images of the new species, a key for identifying species of Matelea Aubl. in the Yucatán Peninsula, and a distribution map are included.

Marsdenia (Apocynaceae: Asclepiadoideae, Marsdeniae) is represented by five species in the Mexican Yucatan Peninsula (vs. seven in the whole of the province), one of which is herein proposed as new to science.  The new species, Mardenia calichicola Carnevali & Juárez-Jaimes, is only known from a narrow strip of sub-xerophytic forests over calcareous, rocky soils along the northwestern edge in the Yucatán state of Mexico. Marsdenia calichicola is morphologically similar and likely related to M. gallardoae and M. trivirgulata. Among other characters, it differs from Marsdenia gallardoae by the presence of a corona composed of cushion-like calli (corolla lacking calli in M. gallardoae) whereas M. trivirgulata has a glabrous or glabrescent corolla (vs. pubescent in M. calichicola); additional characters are herein discussed. We provide pertinent iconography to aid in the identification of the new species plus a key to diagnose the three species in the M. trivirgulata complex. The conservation status of the new taxon is assessed against the IUCN criteria as CR. A distribution map and a key to the species of Marsdenia from the Yucatan Peninsula Biotic Province are presented.

A new species of Triacanthoneus Anker, 2010 is described from an anchialine cave near Akumal, Quintana Roo, Mexico.Triacanthoneus akumalensis sp. nov., is the fourth species in the genus and can be distinguished from the previously de-scribed species by the position of the sharp lateral teeth on the carapace, the length and shape of the rostrum, the eyes beingcompletely concealed by the carapace, the dentition of the major chela fingers, and the shape of the telson. The presenceof a pleural process in the new species represents a new character for the genus. The description of T. akumalensis sp. nov. increases the number of caridean genera having representatives in the anchialine systems of the Yucatan Peninsula to 11.

We describe a new species of coralsnake, Calliophis castoe, from western peninsular India. The discovery of this new species comes as a surprise because it is a venomous snake from both lowland and mountainous areas that are accessible and well populated. The new species differs from all other Calliophis, the Tropical Asian coralsnakes, in having unicolored and dark body and tail dorsa, an orange head band, a salmon color to scarlet body and tail underside, four maxillary teeth behind the fang (the highest number, except for some individuals of C. maculiceps) and, in having the prefrontals touching the third supralabial while having both a preocular and a nasal (except for some C. beddomei). Calliophis castoe also differs from all other Indian coralsnakes, with the exception of some Sinomicrurus macclellandi, in having an unpatterned body, no dark pigmentation on the last supralabial, and a wide post-temporal band. We also present mitochondrial DNA sequence differences between the new taxon and C. nigrescens. The new specie is the second species of coralsnake known from the state of Goa (beside C. nigrescens), the third known from Maharashtra (beside C. melanurus and C. nigrescens), and the fifth known from the state of Karnataka (beside C. beddomei, C. bibroni, C. melanurus, and C. nigrescens).

A New Species

A new species of Hechtia from the Mexican State of Tamaulipas is herein proposed as new: Hechtia hernandez-sandovalii, which is known only from the municipality of Villa de Miquihuana in the southwestern portion of the state. The new species is easily recognized by the following combination of characters: its white cotton-like indument (turning brownish with age) on the branches, rachis, and peduncle of both staminate and pistillate inflorescences. The new taxon is compared with H. glomerata, a species morphologically similar.

In the Yucatan Peninsula of Mexico, 95% of the human cases of Cutaneous Leishmaniasis are caused by Leishmania (Leishmania) mexicana with an incidence rate of 5.08 per 100,000 inhabitants. Transmission is limited to the winter months (November to March). One study on wild rodents has incriminated Ototylomys phyllotis and Peromyscus yucatanicus as primary reservoirs of L. (L.) mexicana in the focus of La Libertad, Campeche. In the present study, the prevalence of both infection and disease caused by L. (L.) mexicana in small terrestrial mammals were documented during five transmission seasons (1994-2004) in five foci of Leishmaniasis in the state of Campeche. Foci separated by only 100 km, with similar relative abundances of small mammals, were found to differ significantly in their prevalence of both symptoms and infection. Transmission rates and reservoir species seemed to change in space as well as in time which limited the implementation of effective control measures of the disease even in a small endemic area such as the south of the Yucatan Peninsula.
